我们的身体依靠极其敏感和精致的温度控制系统来维持健康和体内平衡状态。人类从事的极其广泛的身体活动和我们面临的各种环境条件需要出色的策略和机制来调节内部和外部传热过程。在身体遭受创伤的情况下，治疗性温度调节通常是逆转损伤和炎症并启动一系列愈合的首选方法。人体体温调节的重点是将身体核心温度维持在一个严格的值范围内，即使内部能量产生率可能会在一个数量级上变化，环境对流和辐射热负荷可能会在没有任何显着的个人控制的情况下发生巨大变化，表面隔热层可能会被添加或去除，所有这些都发生在人体内部恒温器遵循可能因疾病和麻醉剂而改变的昼夜节律周期时。对人体复杂生理功能和控制的高级理解可以与传热分析和设计技能相结合，以开发救生和治愈伤害的医疗设备。本文将描述作者在维持健康和增强愈合过程的传热实践方面所经历的一些挑战和征服。
Our bodies depend on an exquisitely sensitive and refined temperature control system to maintain a state of health and homeostasis. The exceptionally broad range of physical activities that humans engage in and the diverse array of environmental conditions we face require remarkable strategies and mechanisms for regulating internal and external heat transfer processes. On the occasions for which the body suffers trauma, therapeutic temperature modulation is often the approach of choice for reversing injury and inflammation and launching a cascade of healing. The focus of human thermoregulation is maintenance of the body core temperature within a tight range of values, even as internal rates of energy generation may vary over an order of magnitude, environmental convection, and radiation heat loads may undergo large changes in the absence of any significant personal control, surface insulation may be added or removed, all occurring while the body's internal thermostat follows a diurnal circadian cycle that may be altered by illness and anesthetic agents. An advanced level of understanding of the complex physiological function and control of the human body may be combined with skill in heat transfer analysis and design to develop life-saving and injury-healing medical devices. This paper will describe some of the challenges and conquests the author has experienced related to the practice of heat transfer for maintenance of health and enhancement of healing processes.
